MSRC_CVE-2021-24032
Vulnerability from csaf_microsoft - Published: 2021-03-02 00:00 - Updated: 2025-05-27 00:00Summary
Beginning in v1.4.1 and prior to v1.4.9 due to an incomplete fix for CVE-2021-24031 the Zstandard command-line utility created output files with default permissions and restricted those permissions immediately afterwards. Output files could therefore momentarily be readable or writable to unintended parties.
